This is a link to the Nippondenso starter - $350 USD
http://www.motoelekt.com/starter.htm  from this page:
http://www.motoelekt.com/ignition.htm  where he also talks about his rebuilding service:
[size=12]"Starters are robust, but over time, the shaft bushings usually develop enough wear to cause internal drag or interference when it tries to turn . This requires too much current from the battery , and frequently there won't be enough left for the ignition system to work . Hard starting can frequently be directly attributed to excessive starter current draw . Starter service includes armature shaft and drive gear bushing replacement, commutator cleaning and truing, brush inspection, and overall cleaning and lubrication. If more serious problems are found, an exact quote will be provided before proceeding."[/size]
Rick is a good guy, and stands behind his products, as a few here will attest.
I am sure he ships to Australia.
The '81 and the '83 used the same starter
part number. Â I don't know if that means they came from the same supplier.
If you don't already have a online microfiche bookmarked on your computer, you should. Â I like RealOEM the best. Â Just put your bike's serial number in the field at the top of the page, and click "browse parts". Â Then save that page to your bookmark, and it will always come up with your bike.
